In devices provided with an evacuated bulb in which is present an activated metallic getter, hydrocarbons can be released or produced. As a result, the gas pressure and the heat conductivity increase. In devices according to the invention, for example, low-pressure sodium vapour discharge lamps, solar collectors, display tubes and image intensifiers, a getter auxiliary means is provided. The auxiliary means comprises an inorganic porous carrier charged with a transition metal having an atomic number from the series 23 to 29, 41 to 47 and 73 to 79, in ele...
1. A device provided with an evacuated bulb in which bulb there are present as activated metallic getter and an auxiliary means for the getter, characterized in that the auxiliary means is capable of disintegrating methane at a temperature of 350° C. and comprises an inorganic porous carrier charged with at least one transition metallic material selected from the group consisting of rhodium, copper, platinum, palladium and oxides thereof. 2. The device of claim 1 wherein the carrier is charged with a combination of at least two of said transition metal m...
